Listen to what a modern statesman has to say on this subject of using a dead tongue for the language of worship.
"There is no Church," says Lloyd George, "that has made a surer and deeper search into human nature. Roman Catholics conduct their worship in the language of worship. Their Church utilizes every means of taking people beyond everyday interests; the language of commerce and of everyday occupation is left outside, and the people are taught the language of worship. That shows a shrewd, deep insight into the human mind."
- The Mass by Fr. Joseph Dunney, p. 38.
This is a fine textbook for all Catholic youth. The above quote is just a taste and get your copy here: http://www.angeluspress.org/.
